LUBRICATOR FOR ELEVATOR-GUIDES.

To all whom t may concern Be it known that I, JOSEPH H. Hinz, a citizenof the United States, residing at Milwaukee, county of Milwaukee, andState of Wisconsin, have invented new and useful Improvements inLubricators for Elevator- Guides, of which the following is aspecilication.

My invention relates to improvements in lubricators for elevatorlguides, and it pertains to that class for which application Serial No.562,354 was filed by me on the 20th day of May 1910. By the device shownin said application, a fluid lubricant is adapted to be lead bycapillary attraction through a wick from a reservoir to lubrieatingpads, which pads are formed of felt or other similar' material, and areyieldingly retained against the opposing surfaces of the elevato-rguides by springs, whereby, as the elevator with which such parts areconnected, moves upwardly and downwardly, said guides will beautomatically supplied with the required lubricant.

It will be understood that a moving elevator has a slight lateral, aswell as a vertical movement, and that the springs by which thelubricating pads are retained in contact with the guides must be ofsufficient length and tension to constantly retain such pads against theguides, and that when so made, the friction of the pads against theguides is such, at times, as to wear away the pads too rapidly foreconomic use.

The object of my invention is, therefore, to provide a resistance memberformed of hard fibrous material or the like, which will be broughtIintocontact with said guides as soon as said pads have been but slightlycompressed, whereby the further pressure of the springs will be resistedby said resistance member, while the pads will bear but slightly againstsaid guides with a constant uniform pressure.

My invention is further explained by reference to the accompanyingdrawings, in which- Figure 1 represents a vertical section of areservoir for a. fluid lubricant, in connection with one of a pair ofelevator guides, showing aside view of the lubricating pads, wicks, andt-he device for retaining said pads in yielding contact with theopposing surfaces of said pads. Fig. 2 represents a front view of one ofthe lubricating pads provided with my resistance member and aSpecification of Letters Patent.

portion of the wick by which the fluid lubricant is drawn from thebottom of the reservoir to such pads, and Fig. 3 represents alongitudinal section drawn on line :1aof Fig. 2.

Like parts are identified by the same reference numerals throughout theseveral views.

1 represents one of the elevator guides with which my device is adaptedto be used.

2 is a reservoir for the fluid lubricant. 3 represents the fluidlubricant in said reservoir.

4 is a lubricating pad which is preferably formed of felt or similarsoft material, and the same is retained in contact with the opposingsurfaces of the guides 1, by the metallic frame 5, and the said pad isyieldingly retained in contact with the opposing surfaces of the guidesby the springs 6, which springs are supported upon the cylindricalmembers 7, between the surfaces of the wick 8 and the supporting member9,

whereby said pad is forced against the op` posing surface of said guide1, by the recoil of said spring. It will be understood that thecylindrical member 7, serves to support and retain said spring inyielding contact with said wick, while the pressure applied to the wickis, communicated to the pad 4 through the pad supporting frame 5,whereby said pad is retained, as stated, in yielding contact with theopposing surface of said guide.

The device, as thus far described, is made substantially as described insaid prior application, and invention herein is predicated moreespecially, as stated, upon the resistance member used in connectionwith said pad. 10 represents the resistance member which is supported bysaid pad, and said resistance member is preferably located at an angleto the vertical near the center of said pad, as shown in Fig. 2, wherebyas the front surfaces 11 of the pad, are slightly compressed by contactwith the guides, the resistance member 10 will be brought against saidguides, and the further pressure against said pad will be therebyprevented. The resistance member 10 is preferably formed of fiber orother similar material which is sufficiently hard and tough to resistthe wear` to which it is subjected a great length of time, whereby thefriction and Wear of the pad 4 is reduced to the minimum. The back ofthe frame 5 is inclosed by the plate 12, and said plate 12 is providedwith two horizontal apertures 13 and 14, for the reception of the wick8, said wick being preferably passed up in the rear of said frame,thence through the aperture 13, thence downwardly between the plate 8and said pad, and thence out through the aperture 141, when the lowerends of said wick are carried below the surface of the lubricant,whereby the lubricant is fed by capillary attraction through said wickto the rear surfaces of the pad, when it penetrates the pad and isconducted thereby to the opposing surfaces of the guides 1, as shown inFig. 1.

While I have shown and described the resistance member l0 as beingpreferably located at an angle to the vertical within said pad and saidframe, it will be understood that said resistance member may be formedat right angles to the vertical across the center or any part of saidpad, when it will serve to resist the pressure of said spring. I,however, preferably locate the resistance member 10 at an angle to thevertical, as

by so doing, it serves to distribute the oil more uniformly to the rightand left across the surface of the elevator guides.

It will be understood, that as the pad is moved upwardly, the lubricantwill have a tendency to pass downwardly toward the right, along theupper surface of the resistance member, and that when said pad is moveddownwardly, the lubricant will in like manner, be distributed in theopposite direction or toward the left, reference being had to Fig. 2.

l/Vhile I have, for brevity of description, described my lubricatingdevice in the singular, it will be understood that such device isadapted to be used upon the opposing sides of the elevatorguides, asshown in Fig. 1.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a device of t-he described class, the combination with a movablelubricating pad, and a pad inclosing frame, of a resistance memberformed of hard fibrous material located at an angle to the verticalwithin said frame, having its exposed surface substantially flush withthe exposed surface of said pad, means for conducting a fluid lubricantto said pad, means for moving said pad over the bearing surface againstwhich said pad rests, and means for yieldingly retaining` said pad andresist-ance member in yielding contact with such opposing surface,substantially as described.

In testimony whereof I afIiX my signature in the presence of twowitnesses.
